About the Airtac GAFC Air Service Unit GAFC400C10ALNWK
This GAFC400C10ALNWK is a two-piece F.R.L. combination: a filter-regulator body paired with a lubricator on a T bracket. The 3/8in port and 1810 g mass place it in the mid-range class, needing a proper panel mount rather than tubing support. Air enters the first body where the 5 um element traps fine particles and the regulator sets pressure to 0.15-0.4 MPa (20-58 psi), then the lubricator adds a metered oil mist last.
The metal bowl (100 cc condensate, 185 cc oil) suits industrial environments, though the catalogue gives no material-specific ratings, so confirm compatibility with your surroundings. The automatic drain clears condensate without operator intervention, ideal for wet or unattended lines. A 1/4in gauge connection is provided since no gauge ships with this model, and the reverse-flow (reflux) valve is fitted per the K code.

Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Where the Airtac GAFC Air Service Unit GAFC400C10ALNWK Is Used
Precision Valve Actuation
Feed a bank of precision pneumatic valves on a packaging line where the 5 um element protects tight clearances and the lower pressure range prevents over-actuation.
Wet Utility Air Lines
Mount on a machine header in a humid plant where the automatic drain clears condensate continuously and the metal bowl suits the environment without needing frequent manual checks.
Low-Pressure Test Rigs
Supply a test fixture that requires regulated air at 0.15-0.4 MPa (20-58 psi) for sensitive gauges or leak testing, with the reflux valve fitted for reverse-flow applications.
Is the Airtac GAFC Air Service Unit GAFC400C10ALNWK the Right Air-Prep Unit?
Choose this GAFC400C10ALNWK when your line needs fine 5 um filtration and lower-pressure regulation at 0.15-0.4 MPa (20-58 psi). The metal bowl is a build choice, not a performance upgrade, and the automatic drain suits continuous operation. The 5 um element traps finer particles than the standard 40 um, but expect more frequent element service. No gauge is supplied, so add one to the 1/4in connection if operators need to read set pressure. The PT thread carries an MPa/psi scale if you fit a gauge. Spares are GAFR400-10 and GAL400-10, both orderable separately. The 1.0 MPa max supply leaves about 0.6 MPa above the 0.4 MPa top of the range, so plan inlet pressure accordingly.
Quick checklist
- ✓ Body size for your peak flow (3/8" here)
- ✓ Standard 0.9 MPa or lower-pressure 0.4 MPa
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Element 40 µm or 5 µm
- ✓ Thread & gauge scale (PT / G / NPT)
Installation & Maintenance Notes
- check Install with the airflow arrow: filter-regulator first, lubricator last.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Fill the oil bowl with ISO VG 32 or equivalent only.
- check Drain condensate before the 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 1810 g unit on its bracket, not on the tubing.
The lubricator adds an oil mist downstream of the regulator. If any part of the line must stay oil-free, use a plain GAFR400-10 filter-regulator on that branch instead of the full combination.
Airtac GAFC Air Service Unit GAFC400C10ALNWK FAQ
This F.R.L. combination operates at 0.15-0.4 MPa (20-58 psi) with a max pressure of 1.0 MPa (145 psi) and proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C. It has a 100 cc condensate bowl and a 185 cc oil bowl, weighs 1810 g, and uses ISO VG 32 lubricant. The 5 um element filters the air, and the automatic drain clears condensate.
The N in the code after the port means no gauge is supplied with this unit. The GAFC400 body has a 1/4in gauge connection, so you can add a compatible gauge if you need to read the set pressure. The PT thread uses an MPa/psi scale for any gauge you install.
